<font face="Times New Roman" size="+2">


Just multiply both sides by *[tex \LARGE x^3].


Remember these facts:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a^n\,\cdot\,a^m\ =\ a^{n+m}]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a^1\ =\ a]


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ a^0\ =\ 1]


John
*[tex \LARGE e^{i\pi}\ +\ 1\ =\ 0]
My calculator said it, I believe it, that settles it
